The bulb comes here in the desk lamp at the computer table that is turned several times a day and most of the day in operation (yes, yes, I know this contradicts now a bissl).
Even when you first turn it was a disappointment. While the "old" lamp a nice bright white and white hinbekam, here comes a tired money from the bulb.
Sure you can get used to it with time. Nevertheless, it is a first familiarization.
Really bad but I find the flickering. Because the bulb flickers slightly. Not always, but every few minutes there is a "flicker". Almost imperceptibly, but if you literally right in front of him, the bulb (it depends here on me and shines on my desk), then that annoys already huge.
Whether this is an isolated case, or getting so I can not judge. Since flicker pretty quickly goes by, there is some might not even notice.
Perhaps you prefer a slightly higher bulb for the "important role" ..
Addendum: Müller Light has offered me to replace the bulb, but also said that such fluctuations may occur through old power lines when other devices start their service (fridge etc). Since I have quite such an old line (however, the flicker occurs sporadically completely) I will probably favor a different bulb.
